Gionzan An’yō-in Chōraku-ji (祇園山安養院長楽寺) is a Jōdo shū Buddhist temple in Kamakura, Kanagawa, Japan.^[1] Famous for its rhododendrons, it was named after its founder's (great historical figure Hōjō Masako) posthumous name.^[1] The main object of worship is Amida Nyorai,^[2] but it also enshrines Senju Kannon, Goddess of Mercy. An’yō-in is Number three of the 33 temples of the Bandō Sanjūsankasho pilgrimage circuit.^[2]

This temple has a complex history and is the result of the fusion of three separate temples called Chōraku-ji, Zendō-ji and Tashiro-ji.^[2] It was first opened in 1225 as Chōraku-ji in Hase Sasamegayatsu by Hōjō Masako for her defunct husband Minamoto no Yoritomo, founder of the Kamakura shogunate.^[1][2] At the time it was a Ritsu sect temple. After being burned to the ground by Nitta Yoshisada's soldiery in 1333 at the fall of the Kamakura shogunate,^[2] it was fused with Zendō-ji, moved to this spot and renamed, but it burned again in 1680.^[1][2] It was then once more rebuilt and a Senju Kannon (Thousand-armed Goddess of Mercy) was transferred to it from Tashiro-ji in Hikigayatsu.^[1]

The great Chinese black pine in the garden is over 700 years old.^[1] Behind the temple there are two hōkyōintō. The smallest is one of Masako's possible graves. The other is the oldest hōkyōintō in Kamakura and a nationally designated Important Cultural Property.^[1] In the temple's small cemetery down the alley in front of the temple's gate rests famous film director Akira Kurosawa.^[3]
